Sorry for answering with a question on a question, but what's the point of having custom (irrelevant to X-Cart) fields in one database?
As xplorer said if a custom feature is developed as a module for X-Cart (that can't be the other way in X-Cart 5) it will be dumped as well.
So, you'll restore your cart to the 100% working state.
